Slam process question

If you are below your SLAM level, you are fine.

Shock level for a SLAM is FC=24 if CYA=60. If CYA = 60 it is safe to swim as long as FC is not above 24. Refer to Chlorine/CYA Chart in pool school.

I have 2 sons who are lifeguards at our local city recreation center pool. The other day, the pool was shut down because the FC level was above 5. (They tell me it was 10 because the automatic chlorinator was left running the previous night). The day after the shut down, the pool was re-opened. Obviously they have a different standard of what is safe for the FC level. Can you comment on this?

They do not recognize the effect of CYA on chlorine. Although things are slowly changing. It took 50 years after we had the evidence that smoking was bad for your health for government to accept it. Here is a thread with good info in it to address this way better than I ever could.

Some public pools, due to archaic codes, prohibit the use of CYA. If no CYA and 10 FC, everyone would quickly have white bathing suits and dry skin.
